I found this site so useful for valuable information. I got approval from I 130 and I am in US with F-1 visa. Can I submit I 485 without immigration number? Also Can I request for the work permit on this basis?
I am glad our site has helped you. You can receive work authorization only when you apply for your I-485 (Adjustment of Status). You can file that only when your priority date is current. Mere I-130 pendency or approval gives you no help unless you are an immediate relative of a US citizen (like spouse or parent).
